Automated assembly line refers to the connection of machines on a production line in accordance with the specified technological process to form a production line that can be automatically controlled and automatically continuous for all procedures including loading, unloading, loading and unloading, processing and packaging. The automated assembly line is composed of basic process equipment and various auxiliary devices, control systems and workpiece transmission systems.
In the automated assembly line, the phototransistor is an important electronic component. The phototransistor is an optoelectronic device developed on the basis of the photodiode. The current phototransistor is made of silicon material. The silicon phototransistor is made of N-type silicon single crystal into an N-P-N structure. The area of the base area of the die is made larger, but the area of the emitting area is made smaller, and the incident light is mainly absorbed by the base area. Like a photodiode, incident light excites electrons and holes in the base area. Under the action of the drift field in the base region, electrons are drawn to the collector region, and holes are accumulated on the side close to the emitter region.
